WASHER-FEEDING MACHINE.

Specification of Letters Patent.

Patent d Julie 24,1919.

Application fi1ed January 18, 1918. Serial No. 212,445.

To all whom it may concern:

Be it known that I, CHARLES J. DE More,

a citizen of the UnitedStates, residing at' the manufacture of suitcases, bags, or other.

containers using a washerto form a head upon the spread end of the rivet.

The leading object of my invention. is the provision of a machine of. the character and for the purpose stated, which will be positive and reliable in action, which will dispense entirely with the use of springs or like means which would easily get out of order, and which will operate in a practical and eiiicient manner. a 1

Another object of my invention is the provision of a machine which will operate with ease and facility in: a thoroughly reliable manner, which will be of simple, du-

rah-1e and inexpensive construction and from every point ofview be practical and desirable.

With the attainment of these and other inherent objects in view, my invention, broadly stated, consists of a gravity supply magazine, a chute into which the washers are delivered from the magazine, a projector for forcing the washers, one at a time, forward in the chute, an anvil mounted in the chute to form a seat for the washer and re ceive the rivet and its blow or impact, and means for operating the projector to move the washers to the mandrel and toreturn the parts to normal position.

The invention further consists of a ma chine of the character and for the purposes stated, embodying novel features of con struction and combination of parts for service, substantially as shown, described and claimed, it being understood that any changes may be made in the construction of machine which come within the scope of the claims.

Figure 1 represents a side elevation of a washer-feeding machine constructed in accordance with and embodying my invention, the supporting structure for the machine forming nopart of the invention and for the purpose of clearness being omitted.

F 2 represents a front elevation of a portion of the machine showing particularly the gravity supply magazine, the 'de-. livery end of the washenfeeding chute, and a part of the treadle-operated yoke.

Fig. 3 represents a vertical central sectional view of the complete machine.

Fig. l represents a sectional view on the line 4% of Fig. 3..

Fig. 5 represents a top plan view of the washer feeding chute, and

Fig 6 represents a perspective view of the slide or projector for forcmg the washers singly to an anvil carried by the chute,

Referring by numeral to the drawings, in which slmllar numerals of reference are employed to denote the same parts in all the viewer i i 1 a The numeral 1 designates a vertical tube extending upward and forming a gravity supply magazine for the washers 2. The lower end of said magazine discharging into the opening 3, of the horizontal washer-feeding chute a, which is covered for the greater partof its lengthby the cover-plates 5 and h, and is formed in its outer end with a seat 7, in which is disposed the anvil 8, upon which the washer is adapted to seat and the anvil receives the impact of the rivet which enters the opening of the washer to spread the end of the rivet and fasten said washer and rivet together; in other words, the washer forms a broad head upon the rivet.

Fitting upon the inner open end 9 of the chute, is the slide or projector 10, which. is formed with the raised portion 11, formed with the passage 12, and has mounted therein the pair of rollers 13, which receive the waved or convoluted end of the arm 14:, of the lever 15, which lever is fulcrumed at 16 in thebracket 17, secured rigidly to the vertical supply magazine and to form a counterweight and return the lever to normal position after a single washer has been fed forward, a weight 18 is attached to the horizontal straight arm 19 of said lever.

From this construction it will be noted that the magazine rises from the feeding chute and Joy gravity deposits the washers into the receiving opening of the chute and the projector moves or feeds the washers singly to the anvil and the lever which operates the slide or projector is actuated by means of the abutment 20, mounted in the bracket 21, formed on the sleeve 22, carried by the crosshead 23, to which at 24 are connected the upper ends of the yoke 24, the arms of which are guided in the extensions 25 of the feeding chute. The yoke 24 is connected at 26, to an 27, which is connected at 28 with the foot treadle 29. When the foot lever 29 is depressedit causes the abutment carried by the crosshead to be disengaged from the waved arm of the lever operating. the projector, and the weight moves the slide or projector forward thereby feeding the washers, one at a time, in a positive and reliable manner to the anvil in the chute. The waved or convoluted arm on the lever forms an important ,part of my invention in that it causes the proper movement back and forth of the slide or projector.

It is evident that I provide a machine ca pable of use in conjunction with riveting machines such as are employed to spread the end of the. rivet in the opening of the washer for certain kinds of work, which machine consists of few parts, insuring simplicity, eheapness and durability, which will prove reliable and efficient and not be subject to breakage or getting out of order, and Whichmachine for the purposes intended will prove practical and desirable from every point of view. I

It will be apparent that the gravity feedupper end of the rod ing tube of my invention is one of the most important features, as the washers are ted down by gravity, one at a time to the action of the slide and such means as springs, weights or equivalent means are dispensed with, and the feeding of the washers is certain and reliable under all conditions.

I claim:

1. A washer-feeding machine, consisting of a gravity supply magazine, a washerfeeding chute into which said magazine delivers, a projector for moving the washer singly in said chute, an anvil. carried by said chute to receive the washer, a weighted lever fulcrumed upon the magazine and having its free arm engaging said projector, and means for moving said arm of the lever to operate said projector.

2. A washer-feeding machine, consisting of a gravity supply magazine, a washerfeeding chute into which said magazine delivers, a projector for moving the washer singly in the chute, an anvil carried by said chute to receive the washer, a weighted lever fulcrumed upon the magazine and having its free end waved or convoluted and engaging said projector, and means for moving said convoluted arm of the lever to operate said projector.

In testimony whereof I ailix my signature in the presence 01 two witnesses.
